TECHNICAL FIELD

The technology disclosed herein relates to video editing software and,in particular, some embodiments relate to systems and methods for asoftware tools platform in a video editing or broadcasting environment,incorporating advanced data management.

BACKGROUND OF THE INVENTION

Video editing and broadcasting occurs with advanced audio-visualcapturing technology. Still or video cameras may be used to captureimage data. Video broadcast feeds are operated under a broad range ofconditions and are equipped with tools to allow for streaming video,including editing tools that allow broadcasters to incorporateaudio-visual content from a variety of sources. For example, a broadcaststream may be equipped with a video camera that transmits live data andcan operate under a broad range of conditions. Data from these differentsources are typically displayed on various display devices within thevideo broadcasting station. These data streams are typically transmittedusing a variety of protocols and formats according to the source deviceand purpose of the data stream. Accordingly, a video broadcast controlstation typically devotes separate resources to the separate datastreams.

To display visual information from data streams, large panel video andmulti-screen displays are commonly employed in such contexts as NetworkOperations Centers (NOCs), entertainment, theaters, and retail venues.Such displays are often referred to as video walls, info walls, datawalls, tiled displays, virtual walls, display walls, or virtual monitorwalls. Large panel video and multi-screen displays provide groups ofpeople with visual information that can be automatically updated, or arefrequently used for enabling collaboration among viewers. Where a largepanel video and multi-screen display is used for group collaboration,there is generally a requirement that the group has the ability toupdate and reconfigure the visual information displayed, which isusually facilitated through a video switch. Traditional video switchesare controlled through a switch box and have only a single point forcontrol access.

Video broadcasts for sporting events can identify and transmit plays inreal time to a sports team fan through the fan's mobile device. Thisincludes video data such as highlight reels, JPEGS, and collated clips.This data is also used to produce web based video, and can also be usedby teams for player training and evaluations. This allows for all teamshave access to video archives online to do opposing team research andplayer evaluations. This technology also allows for video archiving andalternative audio overlay, with the ability to record proxy video inhigh quality.

SUMMARY OF THE INVENTION

Various embodiments of the disclosed technology provide a softwareplatform for video editing and recording that can turn around ahigh-end, professional product in real time. It provides the ability todistribute video from live feeds, such as major league baseball games,as the action is still happening. The platform uses specialized datamanagement techniques to efficiently handle incoming video data streams,making it possible to ingest, edit, log, review and distribute multiplevideo data streams, in multiple formats more cost effectively usingcommodity hardware.

Commercial broadcasting companies commonly take portions of videocontent and repurpose it for distribution on an Internet portal such asHBO GO or on social media platforms such as Facebook so they can reachmore viewers. To do this, broadcasting companies utilize computerinfrastructure that ingests live or file feeds and transcodes them intovarious formats—Main Screen or ABR Multi-screen—, various codec—MPEG2,H264, HEVC—and various resolutions—mobile, SD, HD, UHD. This type ofreal time processing typically requires vast computational resources,including a lot of expensive computer equipment. The disclosedtechnology includes a new approach to managing the incoming data streamswhich eliminates the need for temporary file storage by using an datapipe, specifically an in-memory ring buffer to feed an incoming streamto the various different encoders. Typically, these types of systemsstore a received data stream into a temporary file which is subsequentlyread by each of the various encoders. Since the process of writing andreading a file from a disk drive is relative much slower than accessingthe information from computer memory, the use of the data pipe makesvideo stream processing many times faster.

The use of the data pipe greatly reduces the network bandwidthrequirements and disk requirements and enables sustained high datarates. It also adds the ability to record video content in softwarewithout using a physical recording card. The software recorder isdesigned to run in a virtual machine with limited resources. Virtualmachines allow multiple recorders to run simultaneously on a physicalcomputer. This physical computer can reside anywhere on a network, notjust in the traditional down-link location.

This provides broadcasters the ability to run these software recordersanywhere such as on the cloud or on their own infrastructure. Today,broadcasters typically must run recorders on blade servers which do notscale as well as cloud technology. For example, typically, a broadcastercan handle only a single feed per blade and run only a single encoder.However, using software recorders it is possible to run multipleencoders and multiple recorders per blade. This enables broadcasters togreatly expand the flexibility and the number of streams that they canrecord without having to vastly expand their hardware infrastructure.

Various embodiments of the disclosed technology provide a configurablelive digital video recorder. Input to the recorder is a file or morecommonly an RTP/TS stream with optional Forward Error Correction. Outputfrom the recorder is a configurable mix of H.2641TS, MXF wrapped H.264,Apple ProRes, HLS segmented H.264/TS, and SCC/TTML closed captioning.All outputs can be in live mode, with a minimum of latency.

Other embodiments provide for a computer readable storage medium havinginstructions embedded thereon to cause a processor to perform operationssimilar to those described above with respect to the various systems andmethods in accordance with the present invention.

The imagestream interface module 202 may receive an image stream acquired by avideo camera or the like. Depending on the embodiment, the image streammay be received directly from the video camera, or may be provided byway of one or more components, such as an image stream processingsystem. The image stream received from the image stream interface module202 may vary in resolution, frame rate, format, and protocol accordingto the video camera or the image stream processing system providing theimage stream.

The user interface overlay module 204 may provide a user interface tothe video editing software tools platform system 200, which may includeone or more graphical user interface (GUI) elements presented over theimage stream received through the image stream interface module 202. Forsome embodiments, the user interface comprises a bottom toolbarconfigured to be presented over the image stream, and configured toprovide access to various video editing software tools 206 availablethrough the video editing software tools platform system 200.

The video editing software tools 206 may include one or more videoediting software tools, such as applications or widgets, which can beutilized with respect to the image stream being received through theimage stream interface module 202. The video editing software tools 206platform includes but is not limited to: a video editing device controlmodule 208; an image similarity search module 210; an image streamprocessing control module 212; an image stream tagging and trackingmodule 214; a timer module 216; and an image enhancement module 218.

The video editing device interface module 220 may facilitatecommunication between the video editing software tools platform system200, one or more of the video editing software tools 206, and one ormore various video editing devices utilized in video broadcasting. Theimage stream processing system interface module 222 may facilitatecommunication between the video editing software tools platform system200 and an image stream processing system utilized to process an imagestream acquired by a video camera or the like. Through thecommunication, the image stream processing system interface module 222may transmit control data to an image stream processing system, orreceive an image stream from a video camera as processed by the imagestream processing system. The image stream processing system interfacemodule 222 may include various data interfaces, including wired orwireless network interfaces and serial communication interfaces.

FIG. 3 is a block diagram illustrating the Real-time Transport Protocol(RTP) stream recorder program. In accordance with the preferredembodiment of the present invention, the RTP stream recorder is acomputer program that receives an encoded digital video stream viastandard internet protocols and stores and repurposes the stream inreal-time on a “cloud” oriented device. The recorder can produce a widevariety of output products from the single input stream. Because therecorder has limited hardware requirements, the recorder can run onmodest hardware, or multiple recorders can run simultaneously on morerobust hardware. The RTP Stream Recorder reads the encoded input from anRTP broadcast source 300 with optional Forward Error Correction (FEC)and writes the packets to a Data Pipe 302. Because multicast RTP isbeing received over the Internet, the receiver can run “anywhere”, notnecessarily where the encoder is physically situated. For example, theencoded source is an 100 Mb/s AVC-I/TS stream produced by a multichannelAteme encoder. AVC-I is an archive quality, H.264 encoded, I-frame only(no P or B frames) digital video elementary stream. The encoded sourcealso includes up to 16 channels of MP2 audio and 2 channels of closedcaptioning (EIA-608/708). A transport stream (TS) 300 is the containerformat used to enclose each of these elements into a single stream. TheRTP broadcast is received via a unicast or multicast socket. Theoptional FEC is a 1D or 2D column and row broadcast, where eachdimension is received on separate multicast ports.

The data pipe 302 is a buffering mechanism that consumes the packetsreceived by the RPT/TS 300 process and distributes them as needed, toeach of the components in the recorder process. The data pipe removesthe need for temporary disk space on the device and allows the recorderto run on limited capability hardware including virtual machines. Thepresent invention uses data pipes, which are in-memory ring buffers, onefor each of the recorder components. For example, if the recorder isconfigured to produce MXF 304, HLS 308 and closed captioning 310, thesystem would create 3 named pipes and copy the received transport streamto each. Because each of the recorder components is reading from its owndata source, the component can run at its optimal rate, without havingto wait for or coordinate with the other components. Other data pipescan include ProRes Recorder 306 and Future Recorder 312 data streams.

The recorder can produce a wide variety of output products. Each of theoutput products has unique requirements and implementation of thespecific recorder component is greatly simplified by being able to readits input from its “own” data source. For example, HLS 318 requirestranscoding and multiple output files 324, while MXF 304 only requireswrapping; no transcoding and a single output file 314. Some examples ofoutput products supported are: live and closed MXF 314; Apple ProRes316; HLS with master and IFrame playlists 318; SCC and TTML closedcaptioning 320; and future recorded output 322.

FIG. 4 is a block diagram illustrating the Digital Scissors ServicesOriented Architecture. In accordance with the preferred embodiment ofthe present invention, Digital Scissors is a Service OrientedArchitecture (SOA) that provides for the manipulation of digital videofiles. Commands are sent to the service requesting an action beperformed upon a source and potentially producing an output. A command400 is created by an external process requesting an action by theservice. A command 400 can be an XML document describing the action, aREST API request or a direct library call. Commands include: Cut atimecode range from a source 408 to a destination 410; Grab 1 or moreframes from a source 408 with a specified timecode signature todestination(s) 410; Transcode change the essence or container of asource 408 to a different essence or container. For example, H.264/TS toMPEG4; Melt is the process of trimming the pre-amble and post-amble of arecording; Append a timecode range from a source file 408 onto adestination 410; Wrap a source essence with a container format to adestination 410; Metadata-Info provides the information about theunderlying digital video: frame size, bitrate, format, color space andthe like; and Archive 408 is the near-line storage of archived sourcesand clips.

The commands 400 use SMPTE timecode to identify which frame or of rangeframes is being requested. Timecode is generally present in the digitalvideo source material and make it possible for all observers toreference the same frame. Timecode is what makes frame accurateidentification possible. An example XML command to request the cutting asource file to a destination using a timecode range is:

   <cut>  <in>   <file>/damsamfs1/team1-team2.dv</file>   <timecode>   <start>10:20:22.00</start>    <end>10:20:32.00</end>   </timecode>  <granularity>frame-accurate</granularity>  </in>  <out>   <overwrite>false</overwrite>    <append>false</append>   <file>/damsamfs1/gclips/team1-team2-clip1.dv</file>  </out> </cut>

The Job Builder 402 coalesce all requests into a queue of jobs that areexecuted in parallel but at a configured maximum rate. Invalid requestsare immediately reported to the requestor. Requests are received frommultiple clients and in multiple forms. Each request creates a new Job,the request is parsed and validated. The Job Builder 402, then createsan internal list of tasks needed to accomplish the request and adds themto the Job. The Job is placed in a queue ready for execution by the JobManager 404.

The Job Manager 404 processes the Job Queue and executes ready Jobs inparallel at a configured maximum rate. There are many design tradeoffsthat are configurable within the Job Manager. For example, does therequest want priority execution; should the manager try to minimizeload, memory use or time. Generally, Jobs will have many tasks that areneeded to accomplish the requested action. Tasks within the Job may berequired to execute sequentially. Certain tasks may be able to run inparallel. For example, a task to transcode a clip that was createdduring a cutting task will have to execute sequentially. Each task isexecuted and monitored 406 for failure. When the Job is complete, theresult is reported to the requestor. Each task is specialized anddesigned to accomplish a specific action by the task execution andmonitor 406. For example, there are cutting, grabbing, metadata,transcode, and wrapping tasks. And each of those tasks as specificversions to handle the following formats: H.264, H.265; MPEG 1/2/4; DV25/50/100; Apple ProRes; QuickTime; MPEG Transport Streams; MXF; HLS,M3U8; and SCC, TTML. Tasks are specific to the action being requested.Each of these tasks has specialized versions, depending on the input oroutput format being requested. A task that is cutting a DV100 file hasdifferent requirements from a task cutting an MP4 file. Searching fortimecode is also different for each of the formats, H.264/TS hastimecode encoded into every frame, where MXF just has a start timecodein the header of the file.

Some formats, like AVC-I/MXF, ProRes and DV100 directly support frameaccurate cutting or grabbing. H.264/TS is much harder. As an example,this is an algorithm to support frame accurate cutting of H.264/TS: Findthe TS packet at which the clip starting time-code occurs. This will bethe frame-accurate cut point. From the frame accurate cut point, seekFORWARD in the stream until an I-frame (FWD IFRAME). If the clipstarting time-code happens to fall on an I-frame then it is notnecessary to seek forward. Create the tail clip that includes allvideo/audio data from this I-frame up to the frame-accurate frame thatoccurs at the clip ending time-code. If the clip starting time-codehappened to fall on an I-frame, then the tail clip is the finalframe-accurate clip and the process is finished. From the frame accuratecut point, find the audio frame that synchronizes with the frameaccurate cut point video frame. Create the audio-only audio-head clipthat contains all audio data from this point up to I-frame FWD IFRAME.From the frame-accurate cut point, seek REVERSE in the stream until anI-frame (REV IFRAME) encountered. Create the video-only video-head-Itolclip that contains all video data from this point up to I-frame FWDIFRAME. Note that this video-head-Itol clip should contain exactly 60frames since this is what Inlet uses as the period (2 seconds) betweensuccessive I-frames. Using the FFMPEG application, transcode thevideo-head-Itol clip into a raw YUV 4:2:2 video frame file (YUV RAW).This will give full video data for each frame in the video-head-Itolclip. Note that in this process, all video-head-Itol clip timinginformation is lost. Calculate the number of frames to drop from thehead of the YUV RAW file and create the frame-accurate raw YUV 4:2:2video frame file (YUV FA). Using the FFMPEG application, transcode theYUV FA frame-accurate raw YUV 4:2:2 video frame file into a video-onlyH.264 transport stream video-head clip. Note that this video-head clipwill contain <60 video frames. Change the PTS timestamps in thevideo-head clip so that they match the corresponding PTS timestamps asthey appear in the source video. Recall that the transcoding fromtimestamped transport stream to YUV RAW removed all timing information.The transcoding of the YUV RAW to YUV FA reapplies timing information,however, this timing information is based at time zero whereas theassociated audio clip is timestamped with the original timing data as itappears in the source video. Append the audio-head clip to thevideo-head clip to create the frame accurate head clip that includes allvideo/audio data from the frame-accurate cut point to FWD IFRAME. Appendthe tail clip to the head clip to create the final completeframe-accurate clip.
